Thank You for the improved ratings.
The idea behind such a design was to give an experience of the earlier gaming time. The Jumping is the one thing the we added as a part of a more advanced plat-former.
We will look into the enemy that was floating at the end of the level.
Each power-up has a manual which is shown at the right of the screen but that's something we plan to improve in the future builds.
There are more than 5 weapons in the game which you can find in the chest as per your skill and rarity.
